DRAWBRlDGE FlAlL-LOCK- Specification of Letters Patent.

Patented Mey 14, 1907.

Application filed February 21, 1907. Serial No. 35S58L To all oft/mt t mrtg emu/'arms Be it known that I, EUGENE einen WRA- VEn, a citizen of the United States, residing on Wvoodhavon svenire, Ozone Parli, in. the county of Queens, city am! Stato of New York, have invented certain new and usoifui lnlproveu'ionts in Track End Adjustments for Drawbridges, which .l @all a Drawn bridge Heil-Look, for use on raiiioeds, of which the following is a specific-ation.

My invention relates to certain new and useful iinproven'ients in Jfastening the pivotal end drewl'iridge rail sections to the drewbriilge proper. It is applied to the ends of the drawbridgfe underneath the movable rails. Thernovable rails on a drawbridge are those rails which ineke up the tracks on the ends of drawbridg'es, and called above pivotal end drawbridge rail sections. The ends oi the reils on the pivotal end drawbridge reil sections extend over on to the solid road bed. This is for the purpose oi making s Erni track joint. l/Vhen the drawbrideo is to be swung open these rails must be lifted in order to clear the rails on the solid road bed While the bridge is in the act of Ytnrna ing. These rails are from fourteen to twentgT feet long, more or less, that is, the pivotal end drewbridge reil sot tions.

It is vitally necessary to the prevention of accidents that the pivotal end drawbridge rail sections be absolutely fastened and that every port of the rails of said pivotal end drawbrdge rail sections be present after the drew bridge has been swung open for passing craft. The universal method of fastening the pivotal end drawbridge rail sections on the ends of the drawbridges is accomplished by a single bolt look. This single bolt look is all that fastens the pivotal end draworidge rail section for a distance oi from fourteen to twenti,T feet, beginning to measure from the end oi the drawbridge.

One importent point in my iin rox-*ement is to :fasten the pivotal end drew iridge rail section every two feet more or less apart both before and after the drawbridge has been opened and swung back into place, ready to permit a train to pass over it. After a drawbridge has been opened and closed again, it is possible that several feet of the rails of the pivotel end drawhrideo rail sections inev be missing, being brokenQby i arring or strooi( by passing craft or otherwise, and the remaining rails oi the pivotal ond drawbridgo rail seotions would allow the drawbridge to be looked and signeis to be oleerod, thereby sending the train over an imperfect tinck. lith my device attached this cannot happen. So, enother important. point is that with my devise attaohod every port of the rails of the pivotal end diawbridge rail seotions must be present or else the drewbriflgo cannot be ier-.hed and signals cannot be cleared.

n still further important point in my iniprovonient is that it makes the pivotal end drawbridge rail seotions on all drawbridges to Whit-li it may be applied, as secure as the spiking of the mils upon the solid road bed.

A still further .important point is that I operate niy improvement with one lever. Ii however oooesion calls for it I nifty operato with more then Ono lever. 1 do not confine myself to one lever.

@en-eral statement of the: objects emi notare of my inoeitio7z-The objects of my invention ere:

First-To ooinpei eil the pivotal end drawbri'dge rail sections on the ends of drewbridges to be in their proper end safe position oe-fore the drawbridge een be looked end the signed given for the train to poss over, after the seid drawbridge has been opened for passing ors-it or other purpose. Every part of the rails of the pivotal end drawbridge rail sections must be in proper and absolutely sete position when the bridge is looked or not any of the remaining rails of the said pivotal end drswbridge rail sections een be fastened.

Second-Another object of my invention is to so reiste iny drewbridge rail look to the signal protecting the drawbridgo, so that the signal cannot possibiy be cleared until every art of the rails of the pivotal end drawa bridge reil seotions is in an elnsolutelgAT proper andsafe position for a passing train.

Third-.Another and very importent objeot of in); invention is that it forms a fastening for the pivotal end draiifbridgo rail seotions every two feet more or less, equivalent to that of spiking upon ties on the solid road bed.

Fourth-A still further objeot is that the entire combination used for fastening end unfestening the ivotal end drewbridge rail sections of the (rawbridge, inoiuding both ends of the bridge, from one to s. four track dren-'bridge or more, is ai'eoniplislied by one IOO level'J that salne lever thrown one way will l'asten all the pivotal end drawhridge rail seetions and reversed it will unl'asten them.

[had :.[c-scl'ipttoa of the several 'views of di'flvwingsf--i aecomplish the stated objects hy constructing and associating the elements as illnstratml in the accolnpanying drawings of which i Figure 1 represents the sectional view of the pivotal end drawhridge rail sections ol the drawhridge and a detail view of my invention as applied to the rails of the pivotal end drawhridge rail seetion. Fig. l shows the rotary locks side view, said locks heilig a part ol my inventioii. Fig. 3 shows the plan of the drawhridge and its connection to ahutments, also the general plan top view oi' the application of my invention.. Fig. 3 also shows the application olE my invention in relation to the signals protecting the drawhridge. Fig. '-t is a seetimial view of my invention showing how it is connected with the connection rod, said connection rod heing controlled hy the one lever that operates the entire mechanism of my invention. 'lhis operating lever is shown in` Fig. 3.

Detail description Qfdrawings.-Fig. 1 represents the sectional view of the pivotal end drawhridge rail section and a detail view ol' my invention. a. shows the pivotal end drawhridge rail section in its normal position resting in an iron. channel c. This iron chalinel C. is as long as the pivotal end drawbridge rail section, and is nsed as a reinforcement to the pivotal end drawhridge rail section, as the rail re. s down. into it when the said pivotal ond drawhridge rail section is in its proper position. rlhe pivotal end drawhridge rail section in this Fig. 1 is heldV in position hy the dogs b. b., these dogs in. turn are locked hy the rotary lock d. d., said rotary lock heing attached to the shaft e., said shaft e. is indicated in Fig. 2.

Fig. 2. shows the rotary lock d. side view, together with the end view of shaft e. and edge view of dog b., and side view of part of the rail of the pivotal end drawhridge rail section a.. lt will. he seen in this Fig. 2 how the dog b. is held in its locked position by the rotary lock d.

Fig. 3 shows the plan of the drawbridge and its connection to ahutinents, also the general plan, top view of the ap lication of my invention. It also shows t 1e a plication of my invention in relation to t e signals protecting the drawbrid ge. a. is the top view of the pivotal end drawhridge rail seetion indicated. (1,. in F ig. 1. b. b. is a top view of the dogs indicated b. in Fig. 1. e. is the top view of the shaft indicated e. in Figs. 1 and 2. As is readily seen on drawing Fig. 3, the dogs b. b. can he placed two feet a art more or less,fro1n point f. to point g. w iich is the whole length of the pivotal end drawhridge rail sections on the end of the drawn hridge. At present this same distance ol' pivotal end drawhridge rail section is held only hy the single holt lock. As seen on drawing Fig. 1 thcdogs b. clamp the rail ol' the pivotal end drawhridge rail seetion on the bottoni llange ot' said raily and lorh the said rail into the iron channel r. Fig. 1` lhis is one of the prineipal features ol' my invention, as the rails oi' the pivotal end drawhridge rail seetions with my deviee are fastened with the dogs l). Fig. 1 every two feet apart, more or less, whereas on all other drawhridges the only fastening for the pivotal end drawhridge rail sections is the single holt leek, and this single holt. loek supposed to fasten the pivotal end drawhridge rail seetion for a distance of' `from fourteen to twenty feet,

measuring in from the end of the drawhridge. i. in Fig. 3 shows the conlieetion rod, top view, lil-inging the operation of all the shafts e. to the eontrol of the one lever marked i.

Fig. 4 is a sectional view of my invention showing how the rotary loek (l. d. Fig. 2 on` shaft e. Figs. -1 and 2, locks the dog 7i. b. Fig. 1, said dog bf l. emineeted with the eonneetion rod 7i.. Fig. 3.

Hoi/i to operee.--'I`o operate my device a man sets signal r. Fig. S hy throwing the le ver I. Fig. 3. This saine throw of the lever l. unlocks the connection rod i.. Fig. Si at the point 1n. Fig. 1%. At this point the eonneetion rod t. Fig. 3 terminates and is there locked hy the rod which operates the signal prot'teeting the drawhridge, so that hei'ore anything can he done to ef'leet the lifting oi the pivotal end drawhridge rail sertions or the opening of the drawhridgeJ this signal must he set to danger. Throwing the signal lever l. Fig. 3 unlocks the end of the connection rod It. Fig. 3 at point m. and permits the operator to then throw lever i.. Fig. 3 which lever nnloeks all the dogs b. b. Fig. 1. Pivotal end drawhridge rail sections are then ready for lifting and the drawhridge ready for opening. As the operator throws lever i. Fig. 3 he therehy releases all the dogs b. t). Fig. 1 from the hottoin of the fiange of the rails of the pivotal end drawhridge rail sections on all tracks, allowing said pivotal end drawhridge rail sections to be lifted. As the pivotal end drawhridge rail sections are lifted the dogs b. b. Fig. 1 which rotate on center pins a. Fig. 1 are thrown hack as indicated in the dotted lines Fig. 1 and are thus held hack hy gravity far enough to allow the rails ol thepivotal end drawhridge rail sections to pass out as indicated hy o. dotted lines Fig. 1. The pivotal end drawhridge rail sections thus lifted, the drawhridge is ready for turning or raising. Alter the drawhridge is swung hack or lowered into place as the case may he, then comes the closing of my device. Immediately after the drawhridge itself is swung hack into normal position the pivotal end drawhridge rail section on the ends of the drawhridge are Y,saftig-53.1
